In this channel, the Higgs decays to two \(Z\)  bosons which subsequently decay to four leptons. This is one of the main channels for studying the Higgs at the LHC and is sometimes called the Golden Channel since it provides such a clean signal. Studies in the off-shell region are an interesting way to search for new particles and for bounding the Higgs width [1]}, [2]}, [3]}, [4]}, [5]}. In the off-shell region with \(\sqrt{s}>2M_Z\) , at the lowest order, we need to take into account two diagrams, \(gg\rightarrow H\rightarrow ZZ\)  and \(gg\rightarrow ZZ\)  through a fermion box (i.e. continuum production of \(ZZ\) ) as depicted in figure REF . We have generated these diagrams in MG, with the two \(Z\)  bosons on-shell and with a minimum cut on their transverse momentum \(p_T(Z)>1 \) GeV (for avoiding \(1/p_T\)  singularities [6]}).
